It is an advantage of the invention that：
1st, bubble charging electrode static nozzle of the present invention is rational in infrastructure, and droplet is made by effervescent atomization mechanism first in mixing chamber
Atomization is produced for the first time, produces the droplet of atomization for the first time by inner conical tubulose charging electrode (10) and interior needle-like charging electrode
(9) charge, take like charges, due to the mutual exclusion between electric charge, left in droplet and second atomization is produced when shower nozzle (11) is exported,
So as to refine droplet；The droplet for leaving shower nozzle (11) outlet enters male-tapered tubulose charging electrode (13) and outer needle-like charging electricity
Region where pole (14), charges to droplet again so that produce third time to be atomized in droplet.Charging twice increased droplet and fill
The electric time, the charge-mass ratio of droplet is improve, increased the adhesion of droplet, the utilization rate of spraying can be effectively improved.
2：By that, by the bevel angle that shower nozzle (11) exit design is 40 °, can increase to greatest extent after inspection information and experiment
Scope is sprayed, atomizing angle is improve.
3：Screen pack (2) can effectively filter the impurity in droplet.

Specific embodiment
The present invention will be further described with example below in conjunction with the accompanying drawings
The present invention is supported the use with electrostatic sprayer, as shown in figure 1, the present invention includes feed tube (1), a screen pack
(2), joint (3), No. two feed tubes (4), mixing chamber (5), insulation sleeve (6), conduction copper column (7), bubble generator (8), shower nozzles
(11) inner conical tubulose charging electrode (10) of shower nozzle (11) internal cavity, interior needle-like charging electrode (9), are nested in, miniature are inserted
Seat (12), male-tapered tubulose charging electrode (13), outer needle-like charging electrode (14) composition.Shower nozzle (11) is by insulating material system
Into.A number feed tube (1) of cylinder and No. two feed tubes (4) of cylinder are connected by joint (3), fixed in joint (3)
Screen pack (2)；The bubble generator (8) of No. two feed tubes (4) and cylinder is connected with the mixing chamber (5) of cylinder, and seals；
The inner conical tubulose that device has needle-like charging electrode (9) in uniform 12-24 on shower nozzle (11) inner conical cavity charges electric
Pole (10)；Shower nozzle (11) outlet outside is fixed with the uniform 12-24 male-tapered tubulose charging electricity of outer needle-like charging electrode (14)
Pole (13)；Shower nozzle (11) exit cone angle is 40 °；Conduction copper column (7) connects inner conical tubulose charging electrode (10) and male-tapered
Tubulose charging electrode (13), installs mini jack (12) on outer tapered tubular charging electrode (13).
When specifically used, after liquid flows into No. two feed tubes (4) by a cylindrical feed tube (1) through the filtering of screen pack (2)
Into mixing chamber (5), the gas for compressing is passed through in mixing chamber (5) through bubble generator (8) in some way and is mixed with liquid
Close, and make both that the blister two-phase flow of stabilization is formed in mixing chamber (5), gas-liquid two-phase forms bubble in mixing chamber (5)
Flowing, the intervention of gas increased the flowing velocity of exit liquid, contribute to the atomization of liquid, and gas is at spray outlet pair
The squeezing action of liquid make liquid formed liquidus, and bubble because external and internal pressure difference change drastically expanded directly at spray orifice (8) place
To exploding, liquidus is fried into smaller particle, that is, produce and be atomized for the first time.Mini jack (12) connects electrostatic generator, inner cone
Shape tubulose charging electrode (10), male-tapered tubulose charging electrode (13), outer needle-like charging electrode (14), interior needle-like charging electrode
(9) compound electrode of composition is into negative high voltage, and the drop being atomized through bubble generator (8) is under the effect of the pressure by mixing chamber (5)
Into the internal cavity of shower nozzle (11), because shower nozzle (11) internal cavity infusion channel sectional area diminishes so that flow velocity increases
Plus, and because being nested with inner conical tubulose charging electrode (10) and interior needle-like charging electrode (9) on shower nozzle (11) internal cavity, can be with
Charged directly to droplet, the activity of the powered rear adsorption of liquid increases, liquid surface layer is produced and significantly aligned, and is caused
Reduction in surface tension, unstability increases, and rupture is atomized into small droplet when being sprayed at a high speed from shower nozzle (11) outlet, i.e., second
Atomization.The droplet for spraying at a high speed continues to charge under outer tapered tubular charging electrode (13) and outer needle-like charging electrode (14), enters
One step increased the charge-mass ratio and adsorptivity of droplet, leave male-tapered tubulose charging electrode (13) and outer needle-like charging electrode
(14) due to the reduction of mutual repulsion effect and surface tension between identical charges behind the region of composition, there is third time and be atomized.
Droplet increases by three atomizations, fogdrop diameter refinement, the penetrability of droplet.Because droplet carries identical electric charge, make
Adsorptivity is strengthened under obtaining the electrostatic field between nozzle and target.
In addition to the technical characteristic described in specification, the known technology of those skilled in the art is.
